Observables and conformal properties of dark matter admixed isentropic neutron stars
Arijit Das, Prashanth Jaikumar, Adarsh Karekkat +1
We construct an equation of state for isentropic dark-matter-admixed neutron stars (DMANS) with a hot core and relatively cold crust incorporating self-consistent temperature and D…
Non-standard decays of vector-like top partners in a -Higgs doublet model at the HL-LHC
Tanumoy Mandal, Stefano Moretti, Rachit Sharma
Extensions of the Standard Model featuring both an enlarged scalar sector and vector-like fermions arise naturally in a wide class of well-motivated theoretical frameworks. In such…
Testing varying coupling constants through multi-Higgs production at the LHC
Ulf Danielsson, Rikard Enberg, Gunnar Ingelman +3
We propose the One Scalar Theory (1ST), a minimalist framework where a single real singlet scalar field mediates the dynamical generation of the Higgs self-coupling and the top Yuk…
Photon-initiated enhancements in the pair production of highly charged coloured particles
Tanumoy Mandal, Subhadip Mitra, Rachit Sharma
Strong interaction is typically assumed to dominate the pair production of heavy coloured resonances at the LHC. However, mixed QCD-QED contributions from gluon-photon () init…
Effects of a Brueckner-Hartree-Fock-corrected effective mass on speed of sound, conformality, and observables of dark matter-admixed neutron stars
Arijit Das, Prashanth Jaikumar, Adarsh Karekkat +1
We construct an equation of state describing cold and dense matter in the core of neutron stars which includes an admixture of fermionic dark matter and incorporates nucleon effect…
Machine learning tagged boosted dark photon: A signature of fermionic portal matter at the LHC
Shivam Verma, Sanjoy Biswas, Tanumoy Mandal +1
We use a Hybrid Deep Neural Network (HDNN) to identify a boosted dark photon jet as a signature of a heavy vector-like fermionic portal matter (PM) connecting the visible and the d…
